| Outline of Final Research Achievements |
Nanometer-size or micrometer-size additional structures were fabricated on glass microspheres. Glass microsphere lasers were made from transparent glass-ceramics containing nano-sized crystals or Faraday rotation glasses by using the Localized-Laser Heating method. Optical resonant properties of microsphere with defects like bubble or grating were analyzed by using electromagnetic simulations such as finite element and finite-differential time-domain methods.
